I'm still waiting for a Warhammer 40k one.
Or one with Madoka that doesn't require dices.

oh man Upotte!! or MLP:FiM MMOs!
I used to want a pokemon MMO.

This reminds me, I should check out the Artix Entretaiment 3D, hope it is still going strong.
Or a MMO that has really cute customization and fun gameplay! I would kick puppies for a Hasbro Universe game.
Marvel.
What if Full Metal Alchemy Online?
Imagine a Evangelion game that doesn't suck!

Shy answer: y-yes.

Loud Answer: YES!

Even if most are fated to be shitty, the chances of one of them being cool are worth the pain.
